APPARATUS FOR FUSING THE RIMS OF GLASS VESSELS.

SPECIFICATION forming part of Letters Patent No. 794,755, dated July is, 1905.

Application filed January 12, 1905. Serial No. 240,734..

To all whom, it may concern:

Be it known that I, HEINRICH ERNsr GUs- TAV UI-ILIG, a resident of the free and hanseatic town of Hamburg, in the German Empire, have invented a certain new and useful Method of and Apparatus for Fusing the Rims of Glass Vessels, of which the following is a specification.

This invention relates to a method of and apparatus for fusing the rims of glass vessels, and is hereinafter more fully described with reference to the annexed drawings, in which Figure 1 is a longitudinal vertical section; Fig. 2, a plan; Fig. 3, a transverse section illustrating more or less dia rammatically a burner having a number of jets directed against a series of glasses on a movable track. Fig. 4 is an elevation, and Fig. 5 is a plan, some of the platforms in the latter figure for supporting the glasses being broken away to more clearly show the mechanism for inparting simultaneous translation and rotation to the glasses.

Similar characters of reference refer to similar parts throughout the several views.

It is known to traverse glass vesselssuch as tumblers, beakers, and the like-which rotate on their own axes in a series one behind the other toward a burner, so that the rims, still somewhat rough, meet the flame of the burner and are thereby fused or melted. Under the present invention the burner is so constructed that simultaneously several flames strike from above upon and in part into a number of glasses. If, for instance, the glasses g be moved along an oblong path, as shown in Fig. 2 of the drawings, the burner a is disposed above a part of this path or track I), which burner receives a mixture of gas and air and directs a flame outwardly through inclined slots a, which are preferably inclined in a direction opposite to the direction of travel of the glasses. Thereby the flames burning in the bottom burnerslots strike the glass rims at an inclination from above, and each glass coming under the action of the burner-jets is first met by one flame only on its outer edge, and then after the glass is strongly heated and fed somewhat forward the flame strikes against the inner face of the rim, spreading itself in a net over the entire glass, which rotates continuously but slowly, and so heats the top, inside, and outside uniformly and fuses the same. This is repeated in the case of each. flame beneath which'the glass is traversed. In the usual way the glasses to be fused are set on the guide-track, and the melted glasses are removed from the track, which remains, therefore, continuously in motion. Such mechanism is shown in Figs. 4 and 5, in which A is a suitable frame having a table or shelf 6, and mounted on the frame is a shaft 7, driven from any suitable source of power and by any suitable mechanism, carrying a pinion 8, that drives the gear-wheel 9, mounted on shaft 10, that is supported on the frame. This shaft 10 carries a miter-pinion 11, driving a miter gear-wheel 12 on a vertical shaft 13 and on the upper end of which is a 'star or chain wheel 14. Opposite this chain-wheel 14 is a similar chain-wheel 15, idly mounted on its shaft 16, fixed in the frame. An endless carrier chain or track 11 connects the two chain-wheels, the one 14 imparting motion to the chain or track I). In each chain-link is rotatably mounted a spindle 16, surmounted by a disk, table, or other support 17 for the glasses g. On the lower end of each spindle is a sprocket-wheel 18, capable of engaging with an endless driven chain 19. This chain 19 passes around an idle chain-wheel 20 and a driven chain-wheel 21, that is mounted on a shaft 22, carrying a friction-disk 23. This friction-disk 23 is acted on by a friction-disk 24, slidable but not rotatable on the shaft 10. A spring 25 urges disk 24 into contact with the disk 23.

The operation of the burner is as follows: Each glass comes first under the action of a flame directed against it at an inclination from above, then under the action of a second and even of a third flame, while still subjected to the first flame or flamesthat is, the glass passes under a sea or net of flame of increasing intensity and heatand the rim is therefore thoroughly fused without risk of breaking- The said operation is no more track and guide the same under the burner,

while a burner which is set at a definite height to the side of the path of the glasses can while so adjusted be useful only for glasses of definite and uniform height, as the flames can beat against the rims of suchglasses only and pass under or over the rims of glasses of different height disposed between those at the proper height.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. Apparatus for fusing the rims of glass vessels comprising means for moving and means for rotating the vessels in a row one behind the other, and a burner disposed above said vessels, said burner having a row of slots directed downwardly at an inclination in the direction opposite the direction of movement of said vessels as they enter the flame, substantially as described.

2. In apparatus for fusing the rims of glass vessels, the combination with mechanism for supporting and moving the vessels, of means to direct a flame on the rims of the vessels generally in a direction opposite to the direction of movement of the vessels as they move into the flame, substantially as described.

3. In an apparatus for fusing the rims of glass vessels, the combination with mechanism for supporting and moving the vessels; of means to form and direct a broad or sheetlike flame on the rims of the vessels generally in a direction opposite to the direction of movement of the vessels as they enter the flame, substantially as described.

, 4. In an apparatus for fusing the rims of glass vessels, the combination with mechanism for supporting and moving the vessels; of means to form and direct a flame onto the rims of the vessels, said flame inclined and directed generally in a direction opposite to the direction of movement of the vessels as they enter the flame, substantially as described.

5. In an apparatus for fusing the rims of glass vessels, the combination with mechanism for translating and rotating the vessels; of means to form a broad or sheet-like inclined flame, said flame directed downward and generally in a direction opposite to the direction of translation of the vessels as they enter the flame, substantially as described.

6. In an apparatus for fusing the rims of glass vessels, the combination with mechanism for translating and rotating the vessels; of means to form a plurality of inclined broad or sheet-like flames, said flames directed onto the rims of the vessels downward and in a direction opposite to the direction of translation of the vessels as they enter the flame, substantially as described.

7. In an apparatus for fusing the rims of vessels, the combination with mechanism for translating and rotating the vessels, of a burner above a part of the path of the vessels and having a plurality of transverse inclined slots to form broad or sheet-like flames, said flames directed onto the rims of the vessels downwardly and in a direction opposite to the direction of translation of the vessels as they enter the flame, thereby producing a heat zone into which the vessels enter at increasing and leave at diminishing tempera tures, substantially as described.

8. In an ap aratus for fusing the rims of glass vessels, t e combination with means to rotate and translate the vessels, of means to direct a plurality of sheet-like flames inclined downward and in a direction opposite to the direction of translation of the vessels as they enter the flames, said flames forming a long and narrow heat Zone through which the vessels pass, substantially as described.
